Map View

The map View is the central menu for displaying Thematic and Station layers.

The map view can be changed by zooming in and out or use the pan button to move the viewed area of the map from the navigation section of the Map menu. Zooming in and out is helpful to obtain a better view of specific locations, in particular if there are many station layers each including many stations.

Zooming in on a specific area for viewing more details

Note: The coordinate of the cursor is displayed in the lower right corner of the view.

View station networks¶

One of the principal purposes of MIKE INFO is to view and analyse data records from the monitoring station network. Viewing station data records stored in the database is done by selecting the Map menu.

Select Stations in the Map view¶

Select a station using the Select button to show details about the station. When the Select button is selected (highlighted) you can either click on a station or drag a rectangle to select multiple stations. When stations have been selected, they appear highlighted with a blue circle.

Station details (e.g. time series) are displayed in the areas to the right of the Map View as long as the stations are selected. To unselect, click on a location in the Map View where no station is located and the station information will disappear from the list.

View Thematic layers and Station layers¶

Thematic layers and Station layers to be viewed in the Map View is selected in the Appearance section of the Map menu ribbon.

View thematic layers¶

Click on the Layers drop down list to select the layers for display in the Map View.

View station layers¶

Click on the Stations drop down list to select the station layers to be displayed in the map.

Stations to be displayed can be filtered according to location

Filter stations in the Map View¶

By default all station layers and all stations of a station layer in the database are? displayed in the map view.

Filtering of stations based on the station layer and the locations of the stations can be defined in the Station list in the Appearance section of the Map menu ribbon.

Clicking on the Stations drop down list opens a dialog for selecting and filtering of stations layers according to:

Country: In which e.g. the Country name attribute of the GIS layer specified in the Countries and basins settings can be used to filter according to country;
Basin: In which e.g. the Sub-basin name attribute of the GIS layer specified in the Countries and basins settings can be used to filter according to sub-basin;
Station layers: In which the Station layers are selected.

Example:

Surface water stations in the Kariba catchment are displayed
